1.5x+1120-4x=670
Use the distributive property to multiply 4 by 280-x.
-2.5x+1120=670
Combine 1.5x and -4x to get -2.5x.
-2.5x=670-1120
Subtract 1120 from both sides.
-2.5x=-450
Subtract 1120 from 670 to get -450.
x=\frac{-450}{-2.5}
Divide both sides by -2.5.
x=\frac{-4500}{-25}
Expand \frac{-450}{-2.5} by multiplying both numerator and the denominator by 10.
x=180
Divide -4500 by -25 to get 180.
